SPECIFICATION formingpart of Letters Batent .No. 246,995, datedSeptember 13, 1881. application filed Junefi, 1881. (No model.)

have invented .a certain new-and useful-Improvement in Parlor an dotherHeatingStoves, of which the followingis a-full,.clear,and exact.description, reference being had to the accompanying drawings, forming apartof this specification in explaining its nature, in

- whichtaining my invention.

the heating capacity of a stove, and to also pro-.

vide means whereby a circulation of air is obtained and maintained aboutthe stove and in the room in which it is contained; and these results Iaccomplish by surrounding the ashpit wall with another wall in such amanner that a passage or chamber is provided between the walls of theash-pit and the auxiliary walls,

, into which cold air is introduced at the front of the stove, and fromwhich the air which has been heated therein escapes, preferably at theupper portion of the rear part of the base-that is, the ash-pit-insteadof being surrounded by a single wall or having a single plate at thesides, end, and bottom, has a double wall at the sides, end, and bottom,with a passage or chamber between the walls, into which air may flow ator near the bottom, and from which it may escape at or near the top.

My invention also relates to the construction and arrangement offlue-plates, whereby this improvement is easily and cheaply adapted for1188- A is the ash-pit. Bis the fire-pot. G is the combustion-chamber. Dis the side divingfiue connecting the combustion-chamber with the basediving-fine E, and continuation of said diving-flue D. e 0' (shown indotted out lines in Fig. 6 and in section in Fig. 2) are flue- 1 platesextending from the rear end of the base toward the front and partiallyconverging, leaving, however, a sufficient space between their-front-endsand the frontof the base for the products of combustion topass into the flue E,.which-communicates with the inclined passageE inthe rear ofthe base connecting with .the uptake E The construction sofar describedis like that of ordinary parlor-stoves of this class, withthe exception that the flue-strips ee' are made less high if-the depthof base is not increased.

To employ my invention the plate F is placed upon the flue-strips e e,and the vertical side and end walls, G G G are provided. Thisconstruction of plate and walls may, however, be the walls of theash-pit before the application of myimprovement, in which case I wouldadd to the stove the inner side walls, H and H the end wall, H and thebottom plate, H, the said plate being cast in one piece with the sideand end walls, if desired. Which ever construction is used, whether thewall is built outside the original wall of the ash-pit chamber orwhether the wall is builtinside of the original wall of the ash-pitchamber, there is located between the sets of walls H H H and G G G avertical passage or chamber, M, upon all sides of the ash-pit exceptingthe front, and there is arranged between the two bottoms H and F thehorizontal passage or chamber N. This horizontal passage or chamber Nopens into the vertical chambers by means of the holes or inlets n inthe lower portions of the side walls, H H H and it opens to the outerair horizontally by means of the opening 12, which may be below theledge n of the stove or above it, as desired. The vertical chambers Mconnect with each other, and the rear one preferably is provided withthe openings m between the uptake E in the top plate and the casing ofthe stove, through which the heated air escapes. There may also be oneor more holes, m, in the front of the base communicating directly withthe chambers M, whereby cold air may be admitted to them.

In lieu of the passage n at the front of the stove for admitting coldair to the chamber N, any other suitable inlet may be employed, and

chamber.

It will be noticed that the inner walls of the chambers or passages Nand M separate the passages from the ash-pit chamber, and that they areheated by the radiation of heat from the fire,and thataheatin g-surt'acewhich hitherto has been of no account for heating purposes is thereforemade of avail.

It will also be observed that the outer and lower Walls of the chambersor passages M and N separate them from the base diving-flue E, and thattherefore they are heated by the circulation of the heated products ofcombustion about them. Gonsequentlythecool air intro duced into thechamber N and from thence to the chamber M passes between two heatedwalls, one of which is heated by heat obtained from the ash-pit and theother of which is heated by the heat'in the base tlue or flues, and thatthe entire surface of these walls is heated from the cold-air inlet tothe hot-air outlets. By heating the air in this manner a circulation ofair in the room is obtained, as the hot air rising from the passagecauses the cold air in the room to be thrown down and makes a draft inthe passages, whereby it is drawn between the heated plates or walls, asdescribed.

By this construction the radiating-surface of the baseofastoveisverynearly,if not quite, doubled.

Having thus fully described my invention, I claim and desire to secureby Letters Patent ot' the United States 1. In a parlor or other heatingstove, an ashpit surrounded upon its sides, back, and bottom by twowalls, one of which, in connection with th e walls of the ash-pit, formsa passage through which air from the exterior of the stove may pass.

2. The combination and arrangement, in a parlor or other heating stove,of the ash-pitA and the air-flue M N, surrounding the sides, back, oreither, and bottom of the ash-pit, and surrounded by the basediving-flue E, substantially as described.

3. The combination of the fine-strips 6-6, the horizontal plate F, thevertical plates G G G with the horizontal plate H located above saidhorizontal plate F, and the vertical plates H H H all arranged in.relation to each other to form the chambers M and N, substantially asand for the purposes described.

4. As an attachment for a parlor or other heating stove, the auxiliarycasing consisting of the horizontal plate H and the vertical plates H HH adapted, as described, to be placed within. the walls forming theordinary ash-pit, and to form therewith one or more chambers orpassages, all substantially as and for the purposes set forth.
